Using the values shown in Table 3, move DIP switch positions and the rear panel toggle UP until the total of the UP
positions equals the number “N”.
The easiest way to do this is to work out the settings on paper.
Subtract from “N” the largest position value possible (and note the position as a “1”), then repeat this
using the remaining value of “N” until the remainder is exactly zero. Note switch positions used to add
to the total value as “1” and the positions NOT used as “0”.
C) Use your paper notes of which positions are “1” and which are “0” to set the switch positions for the
desired frequency.
